Hi,
Reverting a buffer in 21.5.28 leaves the buffer's status as modified for me.
Looks like others see it (or probably related behaviour) too:
http://thread.gmane.org/gmane.emacs.xemacs.beta/25004/focus=25015
https://bugzilla.redhat.com/245017 (includes reproducer, Installation file)
Reproducer:
$ echo foo > test.txt
$ xemacs test.txt
RET (or any other modification)
M-x revert-buffer
y
--> the buffer's status is left to modified.

Yeah, I've reported this. I think I have observed other operations
that should not change the modiff but do, but I can't reproduce. I
don't know what's going on, but it goes back to at least 21.5.27
(+CVS-20070324).
Aidan and Mike are the ones to most recently touch the revert code,
but I observe the issue in builds earlier than their changes.

Okay, I’m committing a change that looks, umm, ‘obviously correct,’ that
should address Ville’s problem and may address Stephen’s, but I didn’t get a
recipe to reproduce the latter to better eliminate it. Please keep an eye
out for this issue, and send me personal mail if it arises with a build from
after today.

more into contact with civilization, Dobrinton was bitten by a dog which was
assumed to be mad, though it may only have been indiscriminating. (Saki)

One culprit for buffer-modified can be text properties, possibly in
connection with font-locking.
